My good friend's dog recently passed away, and she has no use for her large dog Frontline. I would like to take this as it would be a big help, but I don't want to hurt my dog. The medication is for dogs 45-88 lbs and my dog is 30 lbs. Do you know if I could just use less of it for her?

Frontline is frontline is frontline. Same exact formula for both cats and dogs, just conveniently packaged to make dosing easier. Use a syringe to draw out the needed dosage for your dog, remove needle from syringe and apply as usual. Tape up the puncture hole in the original package to seal.

At the feral cat clinic we needed anywhere from 70 to 100 doses for cats and we only used the largest dog size package and filled a test tube with several packages, then drew off correct dosage for a cat.

I'd take it and divide it, you can buy the larger size and divide it in half if you have 2 dogs and the weight equals out, in fact I believe eBay sells Frontline kits that you can use (but they may come w/ Frontline which you dont need), otherwise you can use a small disposable syringe to divide it. I wouldnt use the whole thing on your small dog for one dosage but half, yes, have done it w/ no harmful effects and so have friends who have small dogs.

Doseage for a dog that size is 1.34 mL / cc. If you've got a syringe (no needle, just the dispenser) just put the full dose of Frontline in a clean medicine bottle or shot glass or something else of similar size. Pull up 1.34 mL/cc of the Frontline and apply as usual.

In the rescue I only buy the 12 month supply of the largest dose of Frontline and I break it down according to weight.

For anyone else trying to save money - and this way saves a fortune!!! - here is the breakdown:

I would not. I use Revolution and the only use the 20lb. dosage on my 47 lb. dog. There are more than enough toxins in that to kill the fleas, no need to kill the dog as well! We live in a very high, year-round flea area and have never had an issue with the lower dosage.

To save money my vet once had me buy the large frontline and use a syringe and needle to extract the amount I needed for my cats. It saved me a significant amount of money.

Call your vet to get the correct dosage and a needle and syringe.

Oops, I see this has been addressed already. Well, okay add one more to the group that has used Frontline in this manner.
